particularly adapted for automobiles in which generation will only take place in practically the exact proportion to the amount of gas consumed.

A further object is to insure of a full steady light and an immediate cessation of.

gefneration as soon as the stop cock shut 0 My invention consists of an outer casing, a float contained therein and provided with walls depending downwardly from the bottom of the float, a carbid receptacle fitting into the float and having preferably a c'en tral perforated bottomless tube, a top for the I float suitably held in position and having a tube extending therefrom preferably flexible for the most part, a suitable top for the receptacle to the service pipe of which the tube is connected, the service pipe being pro vided with a stop cock and the parts being otherwise arranged and constructed in detail as hereinafter more particularly explained.

Figure 1, is a sectional perspective view of my improved acetylene gas generator. Fig. 2, is a vertical section of the float. Fig. 3, is a vertical section of the carbid receptacle. Fig. 4 is a detail view showing the fastening means for the top of the float.

In the drawings-like letters of reference indicate correspondingiparts in each figure.

A is the main or outer casing and Bis the removable top thereof.

C is a float having a chambered or double wall 0 and an orifice C in the bottom thereof and depending walls C located preferably within the double walls C but below the bottom 0. The outside of the chambered wall fits the wall of the receptacle of the casing loosely or easy and will allow of the escape of gas or passage of water between the wall of the casing and the aforesaid double wall.

D is a carbid chamber, which fits the inner Wall of the chambered wall C snugly and yet easy enough, so that it may move freely up and down therein and be readily withdrawn therefrom. The carbid chamber has a perforated central tube D extending preferably up to about the top thereof and having an open bottom D A supply of water is placed in the casing, so that it is normally at the level of the height shown in Fig. 1, such water extending through the orifice C and up into the perforated tube D.

E is the top of the float, which fits upon a gasket E resting on the top-of the chamv bered .wall C. The gasket may be of rubber or any suitable material and the top E isheld thereon by means of a plate F and set screw F, which extends through a cross bar F held at the ends in hook-shaped ears F attached to or forming part of the upwardly prcflecting flange F at the top of the double wa c G is a bent tube extending outwardly from the top E and H is a flexible tube extending from the tube G to the service pipe I extending through the top B and provided with a stop cock J. Y

K is a deflecting plate secured underneath the top B and having a downward incline toward the center where it is provided with an orifice K.

K is an orifice-located in the top toward the edge of the deflecting plate where it is near to butinside of where the plate is fastened to the top B.

Having now described the principal parts involved in my invention I shall briefly describe its operation and utility.

Then it is desired to generate gas the stop cock J is turned on and the water passes up through the orifice C? and through the perforations of the tube D, so as to permeate the bottom of the carbid, thereby producing gas, which passes upwardly through the carbid and; pipe Grand tube H and service pipe I. The gas as it passes up through the carbid is to a more or less extent purified but I preferably provide aseparate purifier,

which it is not necessary here to describe.

As soon as it is desired to stop the generation of gas the stop cock J is turned off and the gas then generating forces down the water in the tube D and underneath the carbid holder D through the orifice C and thereby below the level of the carbid chamher and thus it will be seen that no more gas will be generated. Should over generation take place when the stop cock is shut off the water will be forced farther downwardly and upwardly around the sides of the float. Should it be forced so far down- Wardly that the gas will pass below the level of the walls C such gas would then pass upwardly around the outside of the walls 0 and between the double wall and the -wall of the casing, thence upwardly through the orifice K and orifice 'K. It will thus be seen that I have effectually provided for any. danger from over generation of gas, whichI find in practice, however, 1s

practically impossible in my form of generator. Any slopping over is absolutely provided against by means of the deflecting plate K as the orifice K of the same is in the center and the orifice K in the top is near the edge of the deflecting plate and consequently no slopping is likely to take place. The carbid as it is beingacted upon y the water is gradually converted to slaked lime from bottom to top.

\Vhen itis desired to remove the ,carbid holder after the carbid is used up all it is necessary to do is to unscrew the stop cock J and the service pipe when the top B may beraised. The set screw F may also be,

I loosened, so as to relievethe pressure of the plate '15 upon the top E, whereupon the bar F may be swung from underneaththe hookshaped ears F and the top may be readily: removed. The carbid holder may then also be readily drawn out and emptied and then refilled again and the parts placed into the position shown in the drawing ready for the generation.

In generating the gas from the carbid the slaked lime, which gradually creeps up the carbid holder is in a drypulverized state resulting, as I believe, from the heat gen erated when setting the gas'free.

lVhat I claim as my invention is:

1. The combination with the main casing adapted to contain water, of a float having the wall thereof corresponding in form to the wall of the casing and provided with. a

. closed bottom having central orifice and a carbid chamber fitting the wallsof the float and provided with a central perforated tube extending upwardly from the bottom of the chamber as and for thepurpose specified.

2. The combination with the main casing adapted to contain water, of a float having the wall thereof corresponding in form t0 the wall of the casing and provided with a closed bottom having orifice and a carbid chamber fitting the walls of the float and provided with a perforated tube extending upwardly from the bottom of the cham-;

ber and a suitable inclosing top for the top of the float and a service pipe leading therefrom as and for the purpose specified.

3. The combination with the main casing adapted to contain water, of a float having the wall thereof corresponding in form to the wall of the casing and provided with a closed bottom having orifice and'a carbid chamber fitting the walls of the float and provided with a perforated tube and a fioat,-a pipe'leading therethrough and -a-'flex- 'ible-pipe connecting-theaforesaid pipe with suitable inclosing top for the top of the the service pipe as and for the purpose 1 specified. w

4. The "combination with the main ca sing adapted to contain water, of a float located therein and having a closed bottomprovided with an-orifice, and a carbid chamber located in the float and provided with a bottomless perforated tube extending upwardly from the bottom of the chamberas and for the purpose specified. V

5. An acetylenegas generator comprising a casin ada ted tocontain water a float in said casing provided with a closed bottom having a perforation and ,a removable closure at the top of the full diameter of the float, a removablecarbid receptacle having an open top located in the floatand provided with an orifice at the bottom, thesaid float having a downwardly extending wall surrounding the orifice in the bottom thereof, whereby theexcess of gas generated lifts the float in the water and is stored inthecham ber within the downwardly extending'walls as specified.
